We wrote this Python program to translate language files (text or json) in apps to other languages using OpenAI's GPT-4. We handle caching outputs from the AI and let you manually change translations if you're not happy with them.
Nice! The stuff where you cache translations to json looks pretty good, big part of the game with gpt-4 is making sure you manage your bill. The couple of cents per word, really explode if you don't pay attention.
